Metric affine gravity with dynamical chronology protection
Moustafa Ismail, David Mattingly
Modified theories of gravity often introduce geometric structure beyond general relativity to address unresolved problems in the gravitational sector without invoking ad hoc matter…

Physical limits on information metrics and quantum gravity as gravitized quantum theory
Per Berglund, Andrew Geraci, Tristan Hubsch +2
There is a long history in both general relativity and quantum mechanics of removing fixed background structures, thereby making observed objects and measurement processes dynamica…

Information Metrics and Possible Limitations of Local Information Objectivity in Quantum Gravity
Per Berglund, Andrew Geraci, Tristan Hubsch +2
Local information objectivity, that local, independent observers can infer the same information about a model upon exchange of independently acquired experimental data, is fundamen…
